Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed April 3, 1905. Serial No. 253,533.

To a/ZZ whom, it may concern:

Be it known that I, GEORGE H. FISI-1ER, a citizen of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Detonating- Canes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to detonating-canes, and one'of the principal objects of the same is to provide a cane having a magazine therein for containing fulminate tablets or pellets and to provide automatic means for feeding said tablets or pellets singly to an exploder at the lower end of the cane.

Another object is to provide a device of this character which shall be simple in construction, reliable, and efficient and which may be manufactured at slight cost.

rThese and other objects are attained by means of the construction illustrated in the accompanying drawings, in which- Figure 1 is a side elevation and partial section of a' cane made in accordance with my invention. Fig. 2 is a horizontal section on the line 2 2 in-Fig. 1, and Fig. 3 is a detail sectionl of the escapement-springs.

Referring to the drawings for a more particular description of my invention, the numeral 1 designates a cane having a removable head or cap 2 and a hollow or tubular magazine 3, An exploder or detonator 4 is mounted to slide on the lower end of the cane, said detonator having an enlarged portion 4', an upwardly-extending sleeve 5, and openings 6 6 at the sides of said enlarged portion to permit the gas to escape after each explosion. Extending through threaded holes in opposite sides of the sleeve 5 are threaded pins 7 7, the inner ends of said pins projecting beyond the inner wall of said sleeve. At opposite sides of the cane and in line with the pins 7 slots 8 are formed, said slots extending entirely through the wall of the cane and communicating with the magazine 3. Springs 9 10 are secured within said slots 8, the spring 8 being secured at its lower end 11 and its upper end being bent at right angles to form a detent 12, adapted to close the magazine 3 when the pin 7 is in its uppermost position or during the explosion of a tablet. The spring 10 is secured at its upper end to the cane, and its lower end is formed similarly to the upper end of spring 9 or provided with a detent 12, which operates reversely to the detent 12, the pin 7 when in its lowermost position pushing the detent 12 inward to close the magazine and hold the body of the tablets back.

The lower end of the cane is provided with a transverse slot 13, which assists in the feeding of the tablets or pellets into the exploding-chamber 14, where they are exploded between the lower end 15 of the cane and the upper wall 16 of the detonator, as will be understood. The weight of the detonator is such that it slides by gravity to its lowermost position when the cane is lifted from the pavement or ground. The escapement device operates to alternately feed one tablet and stop the body of tablets above, thus insuring one tablet in the detonating-chamber every time the cane is lifted from the ground.

From the foregoing it will be obvious that my detonating-cane is of comparatively simple construction, of few parts, is reliable in use, and can be manufactured at slight cost.

Various changes in the form, proportion, and the minor details of construction may be resorted to without'departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isl- 1. In a detonating-cane, a hollow body portion forming a magazine, a detonator slidably mounted upon the lower end of the cane, pins passing through the sides of the detonator, escapement-springs secured to the cane and provided with oppositely-disposed detents, said pins adapted to operate the escapement-springs, substantially as described.

2. A detonating-cane comprising a detonator, a magazine within the cane, and an escapement device actuated by the weight of the detonator and by striking the detonator on the ground to feed a single fulminate tablet in position to be exploded, said escapement comprising oppositely-disposed springs and pins, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
